BAJ6DD0WHFP-TR Application Field and Working PrincipleBAJ6DD0WHFP-TR, introduced by Rohm, is a low-dropout (LDO) voltage regulator that belongs to the Power Management Integrated Circuit (PMIC) - Voltage Regulators - Linear family. The regulator incorporated with an advanced design, offering simple circuit settings and a high ripple-rejection rate, is suitable for use in many industrial, commercial, and automotive-grade power management applications.This regulator consists of an internal adjustment circuit, error amplifier, 1.21V voltage reference, voltage detector, and current-limiting circuit. It is designed to offer precise voltage regulation and extremely low dropout voltage over a wide temperature range from -40°C to 125°C. It also features low quiescent current and is available in a compact 10-pin package for space-saving solutions.The BAJ6DD0WHFP-TR regulator has a maximum input voltage of 28V and provides 1A of continuous output current capable of supplying up to 3A of peak current. Its maximum output voltage is adjustable from 1.2V to 25V, making it suitable for various power management solutions across different industry and automotive applications.The BAJ6DD0WHFP-TR regulator also has an impressive load regulation of ±1%, making it suitable for switching at load current transitions above and below 1A. It also has a minimum electrical characteristic of 50us, offering excellent transient response and stable output voltages. In addition, it provides a fast and accurate response time of 0.2us to -20mV for input voltage variations, making it suitable for applications requiring precise control of the output voltage.The working principle of the BAJ6DD0WHFP-TR regulator begins with the voltage reference. A voltage reference circuit supplies a precise and stable reference voltage to the error amplifier. The error amplifier then compares the reference voltage with the voltage on the output node of the regulator. An output voltage is generated on the output node with the error amplifier regulating the difference between the two voltages. The current-limiting circuit is designed to prevent any excess current when the regulator is switching at higher load transitions. It activates the circuit when the input-output differential falls below 2.5V, preventing any load operation or power surge within the regulator.The voltage detector is used to stop the regulator operation at an overvoltage or undervoltage condition. It activates when the voltage reaches the preset voltage level, switching the regulator off until the preset level is reached. This helps prevent any damage caused due to overvoltage or undervoltage conditions.In addition to its internal components, the BAJ6DD0WHFP-TR regulator also has a wide range of external components to adjust the output voltage and current. These components include the external resistors, voltage control pins, and external compensation pins. The external resistors are used to adjust the output voltage and the voltage control pins allows users to directly control the output voltage. The external compensation pins allow for a stable output voltage, even when the load current changes from 1mA to 3A.In conclusion, the BAJ6DD0WHFP-TR regulator from Rohm is a highly efficient and reliable voltage regulator, designed for use in applications that require precise power management. Its wide range of adjustable output voltages, precise load regulation and current-limiting circuit, and fast and accurate transient response time makes it suitable for various industrial, commercial and automotive power management solutions.
